Show New Telephone Talks' 1000 17PM Bell Telephone Laboraties have a device which will enable business busi-ness machines to "talk" directly with one another at a speed of about 1,000 words a minute. Printed material could thus be sent over lines like those used for telephone purposes, but at a speed sixteen times that of con ventional teletypewriter systems. Information is placed on magnetic mag-netic tape by an electronic computer, com-puter, electric typewriter or other machine. In contrast to holes punched in paper tape used in many ma-ny other automatic machines, letters, let-ters, numbers or symbols are placed on the magnetic tape in the form of magnetized spots. The chief advantage of magnetic tape is that its speed is easily adapted to match the speed with which the signals can be sent over telephone I wires. It also has the advantage of quiet operation.

The person on the "sending" end talks by telephone with the person on the "receiving" end to notify him that the message is to be transmitted. The recipient turns on a receiver mechanism and the sender then starts transmission. An automatic signal indicates when the taped message is completed. com-pleted. The person on the receiving receiv-ing end removes the tape from the machine and inserts it in the office machine for decoding. On an electric typewriter, for example, exam-ple, the mechanism could be arranged ar-ranged to type out the message automatically from the magnetic tape. This would be set for the speed of the typewriter and could be at a faster speed than a typist could attain. The present laboratory models are about the size of office typewriters. type-writers. If they were engineered for maximum compactness, by using us-ing transistors they could be made considerably smaller. Because of its great speed,' the equipment uses the information-handling information-handling capacity of telephone circuits with high efficiency. In many instances, there is no urgency ur-gency requiring that a message !be sent at 1,000 instead of 100 words per minute. But, for a given giv-en amount of information, the machine ma-chine reduces drastically the am-lount am-lount of time the telephone line would need to be used. ! The efficiency of many present business machines is limited by the relatively slow methods of sending the information from one machine to another. With the data subset this transportation hurdle is overcome and a transmission system will be available to meet 'the rapid pace set by electronic data processing. Most present-day business machines ma-chines could be modified to produce pro-duce the required magnetic tape. |
